  gen-def.py: pass headers as arguments so that msys2 can convert posix paths
  
  When one is not using the msys2 python, the header files that are passed in as environment
  variable cannot be found.
  
  https://ci.appveyor.com/project/fonttools/ttfautohint-py/build/1.0.65/job/rkremny4jjid9nl2#L803
  
  This is because msys2 shell and make use POSIX paths (e.g. /c/Users/clupo/...)
  whereas non-msys2 python.exe uses native Windows paths (e.g. C:\Users\clupo\...).
  
  Msys2 will automatically convert command line arguments (but not environment variables) from
  POSIX to Windows paths when calling a native win32 executable, so we pass the header paths
  as arguments instead of environment variables.
  
  This way the gen-def.py script can support both mingw python running in an MSYS2 shell, and
  native win32 python.
